Sud, if you're going to get bookshelves, my suggestion would be the M22s, which are fine for most music(no pipe organ allowed)without a sub in your size room. You can expect room gain to give you good bass to about 50Hz and reduced but still usable output to 40Hz. Study the SoundStage review which first made me aware of Axiom and led to me getting M22s(I can do without an upper-bass hump).

The most recent review of the M3s is in the Audioholics face-off from last week.

Enjoy the music, not the equipment.
